知道了
第10,14,18WA了
求解释
**help！！！**
```cpp
#include<iostream>
#include<cstdio>
#include<cmath>
#define ll long long
using namespace std;

ll ans=1e17;
ll g(ll m,ll p){
ll sum=0;
for(ll i=p;i<=m;i*=p)
sum+=m/i;
return sum;
}
ll g1(ll m,ll p){
ll sum=0;
while(m){
if(m%p==0) m/=p,sum++;
else break;
}
return sum;
}
int main(){
scanf("%lld%lld",&n,&k);
prime[0]=2,prime[1]=3;

}
if(ans==1e17) cout<<"0";
else printf("%lld",ans);
